How to copy or project uvs & (data block) to another object? to use the same UV map in other objects
How i do this ?
Maybe you want to work on your object until it satisfies the lowpoly lod level, then unwrap and duplicate, and add a subdivide modifier with the option 'subdivide uv' off. This way all you object will have the same uv layer – Yvain Mar 30 '16 at 11:22
when I try to do this I did not have a good result, and I do not copy anything, or nothing in a correct way, I do not copy the SEAMS, and when I copy the UVs, this appears
You can try the "transfer data" tool (the modifier also works, sometimes...).
Documenting readings and research
interesting, it seems that I'm not the only one who has had problems with this!
